GAS-BURNER.

'Specication o! Letters Patent.

Patented Apr. 23, 1912.

Application filed October 29, 1910. Serial No. 589,819.

My invention relates to gas burning ap-` paratus, especially for culinary purposes, and to the manner of combination therein.

It consists in a hooded tip from which the gas issues in a circular and diverging form permits rapid expansion in all directions and free combustion, so the carbon of the fuel and oxygen in the air gradually mingle over a large area and under conditions favorable for combustion.

It also consists in means to regulate the quantity of gas or gas and air combined under pressure, also devices tovproduce inductive action in the gas supply pipe and to introduce a supply of pure air therein at a point near t-he burner, also in various constructive devices to apply my improved manner of using gaseous fuel in cooking or analogous uses, as set forth hereinafter, and is illustrated in the accompanying drawing.

Referring to the drawing 2-Figure I is a plan view of a common single stand or support for culinary use and connected parts; Fig. II is longitudinal sect-ion through the center of the same device and Fig. III is a view of the burner or gas diffusing device when detached.

In burning gas of any kind as fuel, when it escapes from a round, square, or other form of orice, in a direct, single jet, the distance of combustion from the issuing oriiices extends beyond the diameter of common cooking vessels. Combustion is also impeded if the burner discharges normal to or against the bottom of vessels to be heated, not only by an irregular disruption and disturbance of the gas, as there is when small multiple issues are employed, but is valso hindered by the effect of the cool surfaces. For these reasons, I provide the appliances now to be described by the aid of the drawing, similar numerals of reference indicating corresponding parts in the different figures.

1 is a frame or support to sustain cooking vessels and 2 grated bars to raise them above the main plate 8 and permit flame to escape.

4L is the burner plate, of dish form, its bottom 5 being set at an angle to suit the diverging form of the flame or ignited gas issuing at 6 and supplied from a pipe at 7 8 is a stop cock to regulate the supply and 9 an induction nozzle, which is inserted in the supply pipe 15, that enables a limited quantity of pure air to be drawn in at 10 through an aperture controlled by a ported ring l1 that can be set to regulate the quantity of air admitted.

12 is a diffusing device that fits loosely in a socket 13 resting on a ledge 14a and can be at any time lifted out and cleaned or adjusted.

The edges of the plate t are turned up at angle at 14 so that in case the ame becomes greater than this diameter, the heat is then directed up around a cooking vessel at the time in use and the heat is not wasted. The flame thus produced entirely consumes all the carbon and there is no soot or residuum of any kind, not even discoloration, as in the case of single jet burners, especially with fuel, when not of the purest kind.

The device here shown, as will be understood, is but one unit of which there can be a series of like construction when a number of cooking vessels are to be heated at once.

The gas used can be of any inflammable kind, such as carburted petroleum vapor or common illuminating gas.

Having thus explained thev objects and nature of my invention, what I claim as new and desire to secure by Letters Patent is l. In a gas burner the combination with a central member having a vertical passage therethrough, said passage having a smaller diameter at its lower portionz than at its upper portion whereby an internal supporting ledge is formed in said passage, of a tip comprising an annular tubular bottom portion seated upon said ledge, a pair of spaced arms extending inwardly and upwardly from said bottom portion, and a horizontally disposed spreader member supported by said arms of greater diameter than said passage and located a short distance above t-he top of said central member.

2. In a gas burner the combination with a central member having a vertical passage therethrough of a tip comprising a ringlike bottom portion, a horizontally disposed spreader plate of larger diameter than said passage, and spaced arms supporting said spreader plate from said bottom portion, means for loosely supporting said bottom portion in said passage with the spreader plate a shortdistance above the top of the central member, and a burner plate extending outwardly from the central member, said burner plate having a convex central portion.

spreader plate from said bottom portion, means for loosely supporting said bottom portion in said passage with the spreader plate a short distance above the top of the central member, and a burner plate eXtending outwardly from the central member, said burner plate having a convex cent-ral portion, said burner plate terminating at its edge in an annular flaring flange.

In testimony whereof, I have hereunto signed my name, at Sausalito, in the county oft' Marin and State of California, this 22nd day of October, in the year 1910.
